DIY/ Homemade Servo driven CNC Milling Machine with Automatic Tool Changer. It’s capable of machining various metals like aluminium, steel, titanium.
The overall build took about 2 year to this point along work and university.
Every part of this build (development/design and manufacturing) was done by myself with the help of basic tools (angle grinder, Drill press ...) and a bench top lathe.
Besides the servo drive and spindle motor, it was a build on a budget. Most of the components are from industry sales. The spindle motor was sponsored by one of the companies I was working for during my bachelor studies (innospiring).

The overall plan of building a CNC Mill evolved during the process. The further I got and the more I learned, the more I wanted to achieve with this. Now it is usable and capable for building small complex prototypes of “high“ precision.

The Automatic Tool Changer was build with a friend of mine, as part of a semester project in university. A 4th and 5th Axis were also developed in the following semester (unfortunately not build yet..).
